CHOKEB HOOK.

Application inea nay 31,

This invention relates to improvements in what are commonly known in the logging industry as choker hooks, and more particularly to hooks of that type used in connection with cables having retainingterrul'es, knobs or Vother enlargements at their yends for effecting the connection of the cable end'k with the hook body. y' y It is the principal object of thev invention to provide a hook of aconstruction that permits an easier and quickerl application ot the cable retaining errule to the hookthan is possible with hooks now generally used, which is less apt to breakage iiruse and which is a practical device, easy toinanipulate andcontains no movable or joined parts.

lMore specifically stated, the objecto the invention resides in theprovision of a choker hook having a slip sleeve at one end through which 'the choker cable is slidably extended and provided at its other end vvith.

a seat against which the retaining errule at the end of the choker cable may engage and with an entrance to Vthe seat which opens to the end of the hookl ask distinguished from' openings `Otherobjects of the invention reside in the various details of construction'that give strength and rigidity to the hook, so that it is practically indestructible. f

A still further object is to so construct the a cable connecting means when it is desired to attach an extension line to the choker cable. k

In accomplishing these and other objects of the invention, I have provided the improved det-ails of construction, the preferred forms of which are illustrated in the accompanying drawings, Wherein- Figure 1 is a side view of a choker hook embodied by, the presentinvention, showing the choker cable extended through the slip sleeve and its ferruled endseated Within the hook body.

Referring `more in detail'to the' drawings n. p'

l designates in itsy 2 at one 'end through o o* ble 3 iis slidably extended. Preferably, the

it and in order/to avoid any undue wear ony the cable. j o o Extendingm parallel, spaced apart rela- 2, are side Wall members body, providing an intermediate open space or chamber "5 through the hook Within which a ret'ainingknob', or errule, 6,' secured on they end of the choker cable,l is disposed When these parts are connected. yThe end of the hook that y:is opposite thatend containingithe sleeve is closed by means of aat wall," 7D

Which'gatone side of 'they axis of thelhook,

is provided with an opening 8 of sufficient f sizeA that the `ferrule 6 may, be passed through ritintothe chanibeij on' attaching l the 'cable to or in detachinfg igt/,from the'k hook, anda slot 9 leads laterally `from this opening inthe Wall 7 `for passage of thejeai y vble 3, butthis slot is of insuiic'ientavidth for passage of the ferrule, so that` vvhenther the inner end of the :terrulewill engage with the Wal17 and thus provide a connection between the cable end and the hook body.

Formed on `the inner side of the side lWalls --ltot thehook, in .opp'ositely disposed relation, vand extending in the axial direction of thehook from the Wall 7 and adjacent the mouth ofthe slot 9, are shoulders l10{-1O Y i y which prevent direct passage ot the terrule from its seat yon the Wall 7 into the opening 8. These shoulders are sulliciently spaced to permitfpassing the cable between them but they serve to retain the errule and they terminate"atV such distance :trom theosleevle 2 as topjerlnit lateral passage `ofthe errule from one side to the other across the shouldersin ren'loving it from or placing itbon itsseat ywithin the hook. `It Will be noted that the` opening8 is inclined With respect to the axial lineof the hook'as a feature of design which ypermits",the base or lower end of the hook bodyto be made smaller ythan would entirety a'choker hook embodied by the present invention; this be? ing cast in; a single piece With ,a slip .sleeve` Whichthe choker ca- .n

sleeve isflared and rounded out at its ends to facilitate movement of thecable through thesleeve portion k -l offthehookw;

Y be possible if the opening were parallel With the axis of the hook. It is also to be noted that there are no slots opening laterally from t-he hook body and that the opposite side Walls are rigidly connected at their lower ends'by the Wall 7 and by the connecting portion at the outside ot the opening 8 designated by reference nun'ieral l2.

With the device so constructed its use would be as tolloivs W'ith the choker cable 8 extended slidably through the sleeve 2, it is placed about the log or load to be moved and the ferrulc 6 at its end is passed inwardly through the opening 8 sutliciently past the shoulders 10 that it may be moved laterally across the shoulders and dropped onto the seat provided by the Wall 7. Tension on the cable then holds the errule to its seat While the shoulders prevent lateral displacement toward the opening 8, and the closed end of the slot 9 prevents movement the other way. In connecting the ferrule end of the cable with the hook body, the errule is moved successively through the positions shown in dotted lines in Figure 2 at a, and c. .A

VTo release thecable only sufficient slack is required to permit the errule to be lifted over the shoulders 10 and then 'K dropped through the opening 8.

As an added feature, which permits the hook to be used as a cable connecting means, such as might be desired in the event the main choker line was not long enough to reach :its load and it Would be desirable to connect an extension thereto, the two side Walls 4 4 are sage 15 through which the tei-rule, or enlargement, as at 16, of an extension cable 17 may be projected. Slots 18 lead laterally from these openingsinto Which `the cable may be passed laterally, so as to seat the ferrule 16 against a Wall of the hook as is shoivn in Fig-ure 1. Retaining bossesQO are provided on ythe outside of these Walls against Which the t'errnlewill engage to prevent its displacement so long as there is tension on the cables 3 and 17. lilith this construction, the main choker line 8 may be rawn out until 'its ferrule 6 seats against an end of the sleeve 2 andthe extension cable connected to the hook body, which, as so used, serves as a temporary connecting means. y

While I have illustrated and described this device as being a choker hook, it is to be understood that I do not Wish to be limited only to this particular use for the reason that by slight alteration the hook could be Well adapted for use as a bull hook. For such use, the sleeve end Would be modified to receive a permanently connected line in place or" the slip connection provided With the choker cable. In the event that it is used as a bull hook the end opposite that provided With an alined -pas-^ `shown containing the sleeve would remain the saine and the extension cable would be connected therewith in the same manner as the connection shoivn in Figure 2.

Having thus described my invention, what .lf claim as neY therein and desire to secure by liettcrs-Patent, is:

1. A hook of the character described having a chambered body portion provided with a wall forming a seat, said Wall having an opening through which an enlargement at'the end of p jected, and a slot leading laterally from the said opening into the Wall for passing the cable to seat the'said enlargement.

2. A hook of the character described having a chambered bodyportion provided With a Wall forming a seat andprovided with an opening through which yan enlargement at the end of a chokercable may be projected, a slot Aleading laterally from the said opening into the seatfor passing the cable to seat the said enlargement and retaining shoulders formed on the sides of the chamber over which the said enlargement must be lifted to seat or unseat it.

3; A k,choker hook body having a chambered body portion `with a slip sleeve at one end through kWhich a choker cable may be extended and a Wall at its other end forining a seat and provided With an opening through which an enlargement at the end of the choker cable may be projected into the chamber, and a slot leading laterally from the opening into the seat or'passing the cable to seat the said enlargement.
